Go into you Account. Under Profile there is a link called viewing activity, Click on that and you will see a list of everything you have watched and the date you watched it. If the Crown is on the list on the right hand side after the Report a Link is a circle with a line through it, click on that to "Hide from Viewing Activity" Then try to watch the Crown again
